The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of determining when it's possible to plant saxifraga is to use the USDA zone info for Bath.

Planting Calendar for Saxifraga

Frost tolerance for saxifraga:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Saxifraga are barely cold tolerant which means that you can start planting them slightly earlier than other plants that might not handle the cold.

The earliest that you can plant saxifraga in Bath is March. However, you really should wait until April if you don't want to take any chances.

The last month that you can plant saxifraga and expect a good harvest is probably August. You probably don't want to wait any later than that or else your saxifraga may not have a chance to fully mature. You can get started a few weeks earlier by starting your saxifraga indoors.

Last Frost Date

The average date of last frost is April 15 in Bath. It might get as low as -15°F during the coldest months of winter.

Since the USDA zone info for Bath may not be accurate from year to year the actual date of last frost can change quite a bit from year to year. Half of the time in Bath you get a frost after April 15 so make sure that you are ready to protect your saxifraga if you have a surprise late frost.
